End of Central Reserve or Obstruction

End of Central Reserve or Obstruction signs are positioned on motorways and dual carriageways throughout Ireland where median barriers, temporary structures, or construction equipment has been removed from the central reservation.

They're commonly found on the M50 Dublin ring road following completion of barrier repair work or crash barrier replacement projects.

You'll see these signs on major routes like the N7 Cork road or N4 Galway road after central reservation landscaping, drainage work, or cable installation has been completed.

They're particularly frequent on approach roads to Dublin Airport and major ports where overhead gantry installation or removal requires temporary obstruction of the central reserve area between opposing traffic streams.

This sign indicates that the temporary obstruction, construction work, or equipment that was previously blocking or restricting the central reservation has been completely removed and normal traffic patterns can resume.

Drivers no longer need to maintain single-file traffic flow or avoid the central area of the carriageway.

The roadway has returned to its normal configuration with full lane availability and standard lane widths.

This sign confirms that the temporary traffic management phase is ending and drivers can resume normal overtaking, lane changing, and positioning without restriction.

It's particularly important for heavy vehicle drivers who may have been unable to use certain lanes during the obstruction period.

While this sign indicates the end of restrictions rather than imposing them, drivers must still comply with normal road traffic rules as the temporary management period ends.

Aggressive lane changing immediately after seeing this sign, before ensuring adequate spacing and safety, could result in careless driving charges with 2 penalty points and fines up to €2,000.

Dangerous overtaking maneuvers in the newly available road space may carry penalties up to €5,000 with potential imprisonment and driving disqualification.

Speed limit signs often accompany these markers, and exceeding posted speeds as traffic flow returns to normal carries standard penalty points and fines ranging from €80 to €2,000 depending on the severity of the violation.

End of obstruction signs are covered in the Irish driving theory test as part of the temporary traffic management section.

You need to understand that these signs mark the transition from restricted to normal traffic conditions, requiring continued caution rather than immediate aggressive lane changes.

Theory test questions may focus on appropriate driver response when temporary restrictions are lifted.

During practical driving tests, response to end-of-obstruction signs demonstrates your ability to adapt to changing traffic conditions safely.

Examiners assess whether you resume normal lane usage gradually and safely, maintain appropriate following distances as traffic patterns normalize, and avoid dangerous maneuvers in the newly available road space.

Understanding the transition from temporary to normal conditions shows mature hazard perception skills.
